Drake, thank you for a very informative post. Though, in my opinion, it shows how you couldn't hold him back, despite all efforts and concerns. This child was going to push his way into university at a very young age.
One thing that surprises me is that the gifted elementary school did not accomodate his needs. That is what I am expecting from Hunter, that they will do the things you had to do, because they are the professionals in gifted. Especially when they are the magnet gifted school.
The NYC public magnet gifted school does the pullouts and subject acceleration as needed. They told us of a grade 1 child that goes to grade 8 for math.
